INTEGRATED SERVICES DIGITAL NETWORK TERMINATING RESISTOR WITH LINE FAULT PROTECTOR

摘要

An integrated services digital network terminator for use in an ISDN network and associated peripheral apparatus comprised of a first electrical connector in electrical communication with an integrated services digital network. A second electrical connector in electrical communication with the first end of a positive temperature coefficient thermistor and the second end of a positive temperature coefficient thermistor in electrical communication with the peripheral of an integrated services digital network. The thermistor thereby preserves the termination function of the network for diagnostic purposes.
